The Forest of Tamtonas

From the introduction:

A lush canopy, drakelings flitting from tree to tree. A hole in the trunk of a tree where two mice work with local ants to create beautiful art. Every level of the Forest of Tamtonas teems with a special kind of magic. Magic that enables all of its residents to communicate with each other and organize as a community. Magic that is quiet and subtle, though it sometimes manifests in spectacular ways. But magic does not resolve the needs of these beings, merely shifts them.
